Always add current user to autocomplete controller to support filter by "Me"
### What does this MR do?
This MR always adds the current user to the autocomplete list of users.
### Why was this MR needed?
Normally only the members from a team or the group are shown in the autocomplete list. However, this prevents a user from filtering issues belong to him/her if the user does not belong directly to either. To make this filtering more usable, we can be sure to add the current user to the list, which the JavaScript code will move to the top of the list.
### What are the relevant issue numbers?
Partial fix#2202

Add an expect call to prevent random Spinach failure
This should help prevent getting the error:
```
Unable to find field "merge_request_title
```
This was happening probably because it takes some time after the "Compare branches" button is hit before the "New merge request" page showed up.
See merge request !882
Attempt to fix the "I should see that I am [un]subscribed" steps
Makes use of Capybara methods that wait. Hopefully this will fix the
random timing-related failures of this step.

Reorder MergeRequestTabs constructor
The tab was being activated before we set the `[commits|diffs]Loaded`
variable, so even when the `/diffs` route is accessed directly, like
from the "Side-by-side" link, the tab was being loaded from its default
source.
Fixes#1887
