Disable `refitSeeds` by default

The enabled refitSeeds might be responsible for 50% of our CPU time in the ITk track finding at the moment because the propagation will not stop at the last seed measurement surface but continues until the path limit is reached. For this to work as expected we need improvements on the Acts side so the fitting will stop at the last surface. Until then we decided to disable the seed refit.

added ACTS main labels

Hi @astefl I believe the KF uses the direct navigator. Shouldn't it stop at the last surface?
