[PATCH] fix breakage in `notmuch-hello-generate-tag-alist' due to `tag:' prefix

[Pieter Praet]

Even though all tests passed, a previous patch [1] seems to have broken
`notmuch-hello-generate-tag-alist', because the latter expects prefix-less tags.

This is a quick'n'dirty patch, thus probably not fit for consumption.
But it Works(TM).
