SOAP: Fix unit tests that were based old behavior

• Don’t expect ETA fields if not enabled
• Don’t expect Project fields if not enabled
• Don’t expect undefined versions to be set on issue.
• testUpdateWithRareFields() was being skipped when time tracking is disabled, though it is unrelated.
• Don’t test profile/build/platform fields if disabled.
• Have default timestamp in bootstrap file to avoid failures in some dev/test envs.
