Philip Korsholm ea3d738823 Feat(medusa): config error handling in loaders (#2514 )

**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)
