Uninstall themes when all theme infobars are gone; not on each infobar's destruction.

There are multiple problems with the current implementation:
- It handles multiple tabs with theme install infobars badly.
- It has a subtle race condition where installing a second theme, and then
  installing the original theme (note: not clicking undo) uninstalled both
  themes.

Instead, only uninstall unused themes when all infobars are closed down.

BUG=none
TEST=Install theme A. Install theme B. Install theme A. Restart chrome. Theme A should show.
TEST=Install theme A in window 1. Install theme B in window 2. Install theme C in window 3. Clicking undo in any of those windows in any order should work.
