Collection property not specified and default collection is not configured

Hey,
I try to use the cblite tool to replicate a database. The database has several collections within the _default scope.

I use the following command to pull the remote database: `./cblite openremote --token "sometoken" --collection _default.collectionname1 wss://example.com:4984/dbname/`
With this I get the error:
```

Error replicating: Collection property not specified and default collection is not configured for this database (/400)
```

What am I doing wrong?

Start with the cblite openremote command and reproduce the reported invocation against a database containing multiple collections in the _default scope. Trace why --collection _default.collectionname1 produces the missing-default-collection and unrecognized-collection errors; done means identifying the cause and documenting or correcting the expected collection syntax or behavior.
