[FIX] web: handle concurrent actions at startup

This commit aims at fixing a random bug on the runbot.

When loading the webclient, if there is no hash, a rpc is done to
read the default action of the user. When this rpc comes back, we
execute the given action (if any), or the first action (typically
Discuss). The navbar is displayed as soon as possible, it doesn't
wait for the first action to be executed. This means that the
user can open the user menu and click on 'My Profile' before the
first action is executed.

Before this commit, if the user clicked before the read rpc on
'res.users' returned, the default action (or the first) one, was
executed, even though the user clicked on 'My Profile' and thus
asked for a specific action. So basically, the user form view was
briefly shown, and then replaced by the default or first action.

Whereas this is a very rare usecase in practice (the timing is
really short), this sometimes made the totp tour fail. However,
even if it is unlikely, the client must be robust and correctly
react to concurrent requests.

This commit fixes the issue by executing the 'My Profile' action
in the DropPrevious. That way, if any 'doAction' is performed,
other pending operations (also done in DropPrevious) are dropped.

This commit also ensures that the "brand name" part in the navbar
(containing the name of the current app) is hidden when there is
no current app, as in the scenario described above, we land in
a webclient with no current app. Note that not being in an app was
something that was already handled, but not at startup.
