Apparently you still have some messages tagged with these tags. You can
get a list of all the tags in all the messages in the database using:

$ notmuch search --output=tags '*'

Or view the "All tags" section in notmuch-hello in Emacs. There you can
also query which messages have these "undesirable" tags.

On the command line, if you wanted, for example, "foo" and "bar" tags
removed from all the messages:

$ notmuch tag -foo -bar -- '*'

Alternatively, do a search for all messages in emacs, and hit '*' in the
search view to tag all messages matching the query. List the ones you
want removed.
