Extbase QueryResult::count() incorrect for strict language mode
When changing the sys_language_mode to strict, the resulting count is incorrect for the following circumstances:
- sys_language_mode is strict
- The current sys_language is > 0
- There is a record for the sys_language which is HIDDEN and has a valid parent_l10n reference
- The l10n_parent record is the DEFAULT sys_language and NOT HIDDEN
I tracked it town to Typo3DbQueryParser::getSysLanguageStatement() this will respect deleted but not hidden when building the language specific constraints.
