Cache is still used even when wind-up configuration inputs change

[samuelwnaylor]

Example

A user has run a wind-up analysis. As part of this analysis, a preprocess.pickle will be created and saved to local cache. The user amends some wind-up configuration inputs (eg amends exclusion_periods_utc on the WindUpConfig) and re-runs the analysis. Currently, the preprocess.pickle cache will be used even though the user inputs have changed, therefore not updating the analysis with the user's new inputs.
