Fix out-of-bound array access (IMAP)

Browse Source 
The IMAP method allows user names with or without a domain part.  For
user names without a domain part, it still tries to access the (then
non-existing) domain, resulting in "Error: Undefined array key 1 at
.../nextcloud/apps/user_external/lib/IMAP.php#85" log messages.
