Changed sync-internals search to a submit instead of incremental

The change was needed because when there was a lot of information to be
displayed, and a if the query was not pasted, then the incremental search
took too long and the partial results rendering was unnecesarily refreshing
the results pane when what was actually needed was just the full query.

Password manager: improve the check for login failure

Before, we regarded any HTML form on the landing page after a login attempt as failure.

After this CL, it's only a failure, if the new form has the same action as the old one.
