[Fix #9060, Shell crash after mailer crash.]

* e-shell-view.c (hash_foreach_destroy_view): Renamed from
`hash_forall_destroy_view'.  Don't free `name'.
(socket_destroy_cb): Use `g_hash_table_lookup()' instead of
`g_hash_table_lookup_extended()'.  Don't free the URI.
(e_shell_view_remove_control_for_uri): Likewise.
(show_existing_view): Use view->uri as the key when inserting the
view.  Remove the old view from the hash when destroying it.
(create_new_view_for_uri): Same here.
