Subject: [PATCH] emacs: When completing tags, offer each tag once

When prompting for one or more tags to add or remove to/from one or
more threads, ensure that the set of tags offered for completion
contains no duplicates.

Some completion packages (e.g. selectrum) will include every member of
the offered list, resulting in the same tag being indicated as a
possibility several times.
