yesod-static: fix test suite with mime-types >= 0.1.2.1 (#1898)

mime-types 0.1.2.1 changed the MIME type of JavaScript files to
text/javascript. In most situation, it is unproblematic to also
allow the old MIME type (application/javascript), so we don't
need to arbitrarily restrict the lower bound on mime-types (this
can still be done by users if necessary).

Resolves #1897.
