Avoid saving the same content in SerializableFile calls

Browse Source 
Normally this should not matter and it does not, but https://github.com/JustArchiNET/ASF-ui/pull/1409#issuecomment-855873098 highlighted a potential enhancement idea in which the caller requests ASF to save the same content as currently exists. Since write operation could emit unnecessary event which forces ASF to start/stop/restart bot/process, I believe that it's justified to add a read operation in front of it to ensure that the file actually needs to be written over.
