Fix bug in calibration when using only daily data

[pat-schmitt]

This is for the current dev branch.

When you try do mb_calibration_from_hugonnet_mb in a gdir which only contains daily data an error is raised because of gdir.get_climate_info() (https://github.com/OGGM/oggm/blob/dev/oggm/core/massbalance.py#L3313). This could be fixed by providing the filesuffix of the daily data, or using the filename of the provided mb_model_class.

Thanks @rodaguayo for reporting!
