Manage the projectVersion field in "Setting.xml" , so it doesn't update with every save or reload

Reference Issue - https://community.smartbear.com/t5/ReadyAPI-Questions/Ready-API-3-42-0-automatically-updates-projectVersion-every-time/m-p/240988/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExBSklETVhHWkdEMTUxfDI0MDk4OHxTVUJTQ1JJUFRJT05TfGhL#M57307

projectVersion value changes everytime a project is saved. When trying to Pull changes from git, setting.xml needs to be committed first, but it re-appears again as a new change, which blocks pulling from git. 

The "Discard all changes", don't really discard the document.
