For other users' profile, keyboard navigation worked only upto 2
items as the third item with '.mention_user' could not be focused.
This was due to href missing from the anchor tag. $.focus() requires
href to be defined, even if it is '#' to focus the anchor tag.
No need to have separate click handler for user_popovers and
message_info_popovers as the same user-id can be extracted similarly
from the target of both the click events.
Another refactor, `sender_info_popover` was confusing as it doesn't
fix into the context of rightbar user popovers so changed it to
`info_popover_actions` since that section of popovers contains popover
actions.
Hotkey reminders in user popovers( i.e. `@` and `R`) should be present
only for sender info popovers, hence for user-mention and user-presence
popovers it will show no such reminders.
Fixes: #8313.
This removes some options when a user clicks on their own profile, and
replaces them with an option to edit their own profile settings.
Front end test adjusted because it was testing an option that does not
appear if a user clicks on their own profile.
Fixes#5075.
