[testcase needed] Creating and applying a tag matching a saved search will not tag the tasks with it

[nekohayo]

OK this is totally a corner case, and probably something that will depend on issue #553, but mentioning it here while I'm noticing it:

1. Have a saved search for "FOO", but no tag named FOO
2. Select a bunch of things that were tagged @bar
3. Ctrl+T, FOO !bar

Result: it correctly removes the @bar tag from selected tasks, but the tag @FOO does not get created, probably because it conflicts with the search tag of the same name. But in theory, to the user, searching for string FOO wouldn't be the same as searching for tasks that have the tag @FOO...

Can confirm. FOO gets autocompleted in the Ctrl+T editor, so it's likely grabbing it from searches. This is basically impossible in the new core, so it will be fixed then.
