Subject: [PATCH] [BUGFIX] Force string casting of $parserList
The method `BackendUtility::explodeSoftRefParserList()` checks whether
`$parserList` is an empty string. This check may fail, as the variable may
be null instead. `$parserList` is now casted to a string, which converts
null to an empty string.
Resolves: #78858
Releases: master, 7.6
