Fit parameter settings in Pulsed Measurement and ODMR module are not saved

[NicolasStaudenmaier]

What is affected by this bug?

In the Pulsed Measurement and ODMR GUI edited parameters for a fit are not kept when module is reloaded or Qudi restarted. For example I want to make a sine fit with a fixed phase and set the phase not to be fitted. This setting is not restored when I load the module the next time.
master branch, version d62bff5

When does this occur?

Every time the Pulsed Measurement or ODMR GUI is reloaded or Qudi is restarted.

Where on the platform does it happen?

Pulsed Measurement and ODMR GUI

How do we replicate the issue?

Add a fit in the fit settings, edit its parameters, reload the GUI

Expected behavior (i.e. solution)

The edited parameters should be kept in the next session.
