Confirm a share also by pressing enter on the input field

Besides confirming a share by clicking on the confirm button now it is
possible to do it by pressing enter on the input field.

Clicking on the confirm button implicitly hides the autocomplete
dropdown. On the other hand, pressing enter on the input field does not,
so the autocompletion must be disabled and closed when the confirmation
begins and then enabled again once it finishes. Otherwise the
autocomplete dropdown would be visible and it would be possible to
interact with it while the share is being confirmed.

The order in which the input field and the autompletion are disabled is
important. Internally, the autocompletion sets a timeout when the input
field is modified that requests the suggestions to the server and then
shows them in the dropdown. That timeout is not cancelled when the
autocompletion is disabled, but when the input field loses its focus and
the autocompletion is not disabled. Therefore, the input field has to be
disabled (which causes it to lose the focus*) before the autocompletion
is disabled. Otherwise it could happen that while a share is being
confirmed the timeout ends, so an autocompletion request is sent and
then, once the share is successfully confirmed and thus the
autocompletion is enabled again, the request is received and processed.
