Changing Time Series configuration in Ecosim should clear Ecosim results

[jeroens]

The Ewe6 protocol is that whenever input data changes, output data relying on those inputs should be cleared. This does not happen when changing the TS configuration.

To reproduce:

1. Load model, load Ecosim scenario, Run Ecosim
2. From the Ecosim menu, select a Time Series data set to load and press OK

The Run Ecosim plot should be cleared

1. Run Ecosim again
2. From the Ecosim menu, enable or disable a few Time Series and press OK

The Run Ecosim plot should be cleared
