fix: Quick fix whitelabel script error

[rnr]

Fix whitelabel script execution after commenting out Fullstory function - added pass into empty if
Without this script produces error:

  File ".../config_script/whitelabel.py", line 572
    else:
    ^
IndentationError: expected an indented block after 'if' statement on line 569
... % python3 config_script/whitelabel.py --config-file=../edx-mobile-config/openEdXAssets/whitelabel.yaml

Also updated regex to find the development team in the project file, as it could be empty
