EC60to30wISC defaults to 80 levels

[xylar]

The EC60to30wISC test case in COMPASS defaults to 80 levels, whereas it needs to be 60.

The issue also applies to the QU240wISC test case. It is related to trying to reuse the same initial_state.xml file for all test cases, whereas each test case needs its own.

Fixed (I believe) by #502. Fixed somewhere for sure.
