[BROWSEUI] Fix mistake (IDR_EXPLORERBAND -> IDR_FILESEARCHBAND) (#7210)

JIRA issue: CORE-19705
#7163 (960a305) made a regression on DllRegisterServer.
The cause is lacking IDR_EXPLORERBAND that
CSearchBar wants.
IDR_EXPLORERBAND for CSearchBar is a mistake.
- Use IDR_FILESEARCHBAND resource instead of
  IDR_EXPLORERBAND resource for CSearchBar class.
