Fixed selection of some layers when layerRecord was null.
Fixed selection in map.
Removed .pdf so it's not duplicated in the output.
* Improved loading message with i18n and spanish translation in Parser.js.
* Added option for disabling removal of layers of loaded groups.
* Fixes to layer removal (fixing part of #78184 and #78182).
We don't let unlogged users to remove layers from geoserver.
We only enable the "make persistent" option for those layers that are temporal. Improves #78184.
