Title: fixes #6511 / BZ 1109085 - content host bulk errata fixes

This commit addresses a couple of small UI issues with the
content host bulk errata action. The issues were:

1. If no content hosts are selected, do not retrieve applicable
errata from the server. The API requires the user to provide
at least 1 content host; therefore, no need to send the request
with 0.
2. If no content hosts are selected, disable the refresh and
install actions.
