Allow calib_analyze_all to run when there are no previous analyzed bumps, etc.

This avoids:

  Traceback (most recent call last):
    ...
    File ".../calibcant/analyze.py", line 410, in calib_analyze_all
      bumps[i] = sensitivity
  TypeError: 'NoneType' object does not support item assignment

which can happen if you construct the calibration datafile by hand and
have not yet analyzed it with calibcant.
