Fix Integration Tests being run on Appveyor

Might also be a good time to wrap up in parallel with this.

The fix was to make the appveyor script force move the decrypted .synapseConfig file.

Since we started adding a default synapseConfig to the home folder file which the move command won't overwrite unless the -force arugment is used

Is this ok to close out or is there still work to be done here?

I would have to ask for this issue since she's been working on the Python client recently. If the Appveyor tests (that used to pass) are not passing recently we may need to investigate.

I have not experience integration test failure on AppVeyor.
