automated smart wallet provision test not reliable

[dckc]

Describe the bug

The automated test for starter IST from the provision pool (#6067) is a little flakey. It works ok when invoked as yarn test test/test-make.js test/test-make.js -m '*provision' but we seem to get timing issues when run with the other integration test there: yarn test test/test-make.js.

So as discussed, we're marking it with test.skip.
