newRxError is not a constructor

[ghost]

Case

Bug.

Issue

The code here:

rxdb/src/util.js

Lines 197 to 200 in 41cb52e

	throw new RxError.newRxError('UT2', {
	regex: regStr,
	givenName: name,
	});

Uses the new operator on RxError.newRxError, however RxError.newRxError is not a constructor. An additional error is then thrown, masking the original error.
