Building mobile test causes go panic

[borrrden]

This is the command used

./sequoia -test tests/mobile/test_sg.yml -scope tests/mobile/scope_1sg_1cbs.yml --expose_ports --skip_teardown --skip_test --network cbl

I ran it once to get rid of the noise, and this is the result of the second run (the first run also ended in the same way but with a lot more noise). Here is the resulting output:

→ parsed tests/mobile/scope_1sg_1cbs.yml
→ parsed tests/mobile/test_sg.yml
→ Creating network: cbl
→ parsed providers/docker/options.yml
→ start couchbase http://cbs.st:8091

Oh, it's because the sync gateway version is null in the docker provider options...
