Loading the users into the autocomplete provider is quite a large
chunk of work for a large room. Try lazy loading it the first time
a completion is done rather than up front when the room is loaded,
given that a lot of the time you switch to a room you won't say
anything.
Because we need to support tab completing `"@some_user"` if `@some_user` has a display name that is totally different and will therefore not match what the user typed in.
This does have the disadvantage of a display name appearing (the pill) that isn't at all what the user typed in, but the autocomplete box and the tooltip should give enough information to let the user know what's going on. (e.g. typing `@kyr*tab*` and getting `Remmy`).
This _does_ run contrary to vector-im/riot-web#4495

to make sure that the length of text in the decoration (See <Pill>) is equal to the length of text in the completion (underlying text range that the Entity covers).
by index of the query in displayedAlias and then length of displayedAlias. (So that aliases where the query appears earlier in the string appear first and if the query is in the same index for two aliases, the shorter one appears first).
These will appear decorated because they are inserted as entities. It was necessary to modify pills to have an explicit linkText that is derived from the `href` being pillified (and is thus no longer the inserted completion but rather the display name (or user ID) or room alias.
For example, searching for `:tong` will now match `:stuck_out_tongue` because the query `:tong` has all non-word characters removed, becoming `tong` and is then matched against the (long) names of emojis such as `smiling face with open mouth and tightly-closed eyes`.
_sortedUniq claims to be like _uniq but optimised for sorted arrays - https://lodash.com/docs/4.17.4#sortedUniqBy. But in practice this isn't quite true, so stick with the unoptimised version.
This modifies the composer completion such that completing a room or user will insert an IMMUTABLE matrix.to LINK Entity for the range that was replaced. Display names will not have a colon after their name anymore as it seemed strange that we would insert one after a pill.
Use bluebird instead of the now removed "q" library.
Also, make sure we timeout and then `reflect` to effectively do an `allSettled` that waits for all promises to either be resolved or rejected. Then we filter for those that are fulfilled and return the completions.
Otherwise by default it appears first, pushing "people" further down the list
Also, remove "unicode9" category ordering, as this category does not exist as part of emojione
