Subject: [PATCH] Fix not properly resetting needle buffer in
 createTrieFromStoredDomainOpt()

Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1902

The cached needle didn't match the one stored in the
needle buffer when resetting the cached needle without
resetting the needle buffer.
