Feat(medusa): config error handling in loaders

[pKorsholm]

What

• add error handling when loading project config

How

• Add error parameter to get-medusa-config result if an error was thrown (previously we returned an empty config)
• Discussion:
  A different, but equally valid approach could be just throwing the error rather than creating an error parameter. This causes a more ugly output without warnings and changes the api a bit but it would force error handling. wdyt?

Why

• cli would fail with database error databaseMissingDriverError if config was invalid, ex. missing a comma

example (missing , in config)
