Bug(s?) with small temperature jump experiment.

[Peter9192]

To reproduce:

1. Start with default config
2. Add permutation, set initial temperature jump to 0.1 --> this produces a weird/buggy result, perhaps due to too large time step?
3. Set time step to 0.1 --> Vertical profile plot has NaNs; timeseries plots nothing; diff view shows only time step, temp jump has been reset?
4. Set time step to 1 --> Everything works okay again, except that the temp jump is still back to default

It seems that modifying any experiment (reference or configuration) always only saves the latest modifications

[Peter9192]

shouldDirty={true} means only modified values are returned.

class-web/apps/class-solid/src/components/ExperimentConfigForm.tsx

Line 45 in ec463bb

shouldDirty={true} // Don't return empty strings for unset fields

Now, we're simply overwriting the old config with latest updates:

class-web/apps/class-solid/src/components/Experiment.tsx

Line 114 in ec463bb

const { title, description, ...strippedConfig } = newConfig;

We should either update instead of replace the config
or set shouldDirty to false and prune the defaults after submission.

#88 fixes the issue of multiple config modifications, so now we're left with buggy behaviour of class for the settings discussed above.
