Running stuart_ci_build outside of edk2 tree deletes lots of files

["Rebecca Cran" <rebecca@bsdio.com>]

I know it probably isn't expected/supported, but I noticed that running 
stuart_ci_build outside of the edk2 tree causes it to delete a lot of files:

I ran the following from one directory above edk2:

~/.local/bin/stuart_ci_build -c edk2/.pytool/CISettings.py 
TOOL_CHAIN_TAG=GCC5

And afterwards, "git status" reported:

Changes not staged for commit:
   (use "git add/rm <file>..." to update what will be committed)
   (use "git restore <file>..." to discard changes in working directory)

I also got build errors such as:

ERROR - Build.py #000 from 
/home/rebecca/src/uefi/edk2/CryptoPkg/Test/CryptoPkgHostUnitTest.dsc(35): 
File/directory not found in workspace
CRITICAL - Build failed
