Enable find in page buttons based on search text rather than match

Enable find in page buttons based on search text rather than match
results.

When you re-open the find bar and it's prepopulated with a previous
search, we don't execute a search until you press enter or
next/previous. Before this patch, next/previous was disabled when you
have prepopulated search text but no actual search.
