Fix Xcode CLT path if both CLT & Xcode is installed

[RMinibaev]

If Xcode Command Line Tools is installed at the moment of playbook execution and xcode-select path is set to CLT, then step Get Installed Xcode version would fail with xcodebuild error:

localhost                  : ok=7    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0  

This newly added step assures that xcode clt path is set to actual xcode installation
