Fixes composer warnings when: a) mentioning groups ("By mentioning @group, you are about to notify x people...") and b) mentioning users in a PM ("You mentioned @user but they won`t be notified...")
Currently the theme is matched by name, which can be fragile when there are many themes with the same name. This functionality will be used by the next version of theme CLI.
If for some reason `Discourse.store.path_for` returns `nil`, the
forum would throw an error rather than returning 404.
Why would it be `nil`? One cause could be changing the type of
file store and having the `url` field no longer be relative.
Ember3 is more picky about having a container being destroyed and it's easier to cause exceptions, especially in tests.
This fix has been initially created for an exception occuring in tests when running discourse-code-review and discourse-polls tests at the same time. `getCurrentUser` method body was failing as the container was destroyed.
Original stacktrace:
```
"Error: Assertion Failed: expected container not to be destroyed
at new EmberError (ember:2929:31)

Somehow a plugin or some new Chrome bug is causing its heuristic to detect
our textarea for the composer as a target for address autocomplete
This is likely a chrome bug but this change is very safe regardless.
This does not serve any technical purpose. It is there to provide a signpost for any user/developer that wants to know what to do with a theme archive.
This commit copies `login_required.welcome_message` translation override to `login_required.welcome_message_invite_only` if the `login_required.welcome_message_invite_only` override is blank. This is done so as to ensure that login page customization remains same after [this commit](93eb0a0690).
