Catch RegexException in subscriber count extractor

Browse Source 
When the subscriber count extraction fails to find the Regex pattern,
a RegexException is thrown. This is not a fatal error in most cases,
for example when downloading the channel page in order to update the
user's subscriptions, and so the correct behavior is to return
UNKNOWN_SUBSCRIBER_COUNT.

Related issue: https://github.com/TeamNewPipe/NewPipe/issues/11353.

This bug comprises two issues: subscribers cannot be extracted for
channels with pronoun tags, and when the RegexException is thrown,
channel subscriptions will fail to update because the exception is
uncaught. This commit fixes the latter aspect of the issue.
