RTE improve FE check for writeTemporaryFile
The check reagrding FE Mode for writeTemporaryFile in RteHtmlAreaApiBase does only check for existing TSFE object, however, that isn't enough because another extension could have a crated such a object in the backend
and not removed it correctly.

Can be tested by installing https://github.com/TYPO3-Solr/ext-solr/commit/b04ea3b4cdce9c19e754f47bb6f2c327f2e2fb5b, then:
1.) Open content elment
2.) save content elment (without close)
After saving RTE-Linkhandler won't open because temporary file cannot be loaded (solr adds information to index queue and generates a TSFE object to read configuration but doesn't clean it up in that commit)
Not sure if it can be verified without a solr host being configured though.
