When building a FlexBuffer using the Builder and adding data that exceeds the default buffer size (2048 bytes), in _newOffset() a larger buffer is created, but never used. This results in a RangeError. Resolve by actually replacing the too small with the new larger buffer. Add a test that verifies this by adding multiple large strings to a vector.

When building a FlexBuffer using the Dart Builder API and adding data that exceeds the default buffer size (2048 bytes), in the _newOffset() method a larger buffer is created, but never used. This results in a RangeError.

This was originally reported to us by a user, so additional details can be found in objectbox/objectbox-dart#786 (note that for the reporter the data written that exceeds the buffer size is an integer and in my test a string, so the stack traces and error messages vary slightly).
