TYPO3 Core

Currently revExplode will return an invalid value in this case:

1. $count is set to 2
2. $delimiter does not exist in string

Example:

GeneralUtility::revExplode('_', 'test', 2),

Will return

array('', 'est')

but should return

array('test')

This also leads to an error in \TYPO3\CMS\Core\Resource\Filter\FileExtensionFilter->filterInlineChildren() when updating file reference records in a content element:

#1317178794: No fileusage (sys_file_reference) found for given UID.

because one letter is cut off from the UID.
