Issue with project names containing spaces

[ileitch]

Hello,
Just updated to Periphery 2.19, but now the same command that worked in 2.18 is producing an error:

Command:

periphery scan --skip-build --index-store-path '[REDACTED]' --project '[REDACTED]' --schemes '[REDACTED]' --targets '[REDACTED]'

Error:

* Inspecting project... error: Shell command '/bin/sh -c xcodebuild -project '[REDACTED]' -list -json' returned exit status '65’:

Anyone else running into this?
