Provide more information when build folder creation failed

[tyuldashev]

Description Currently when UTBot fails to create build folder it doesn't provide too much information to user to fix this problem.

To Reproduce

1. Personally I get this error most of the time when accidentally specify wrong project path on remote server or leave suggested by Quickstart wizard. To emulate that set something like /mnt/c/ in the UTBot settings for Project Path on Server
2. UTbot suggests to create build folder, accept suggestion - creation fails with error - Permission denied

Expected behavior

• Add to error message exact path to build folder which UTBot tried to create
• Suggest to verify Project Path on Server setting
