Fix string comparison in deploy.sh

[mo-nathan]

This should fix the reported error: script/deploy.sh: line 45: [: too many arguments

Hmm. 3 CI system test failures. First time I've seen that. (They are identical in the push and pr tests.) Locally, one system test method fails consistently:

@JoeCohen @mo-nathan For the test Joe's getting failures on, I'm pretty sure the test is correct and the wait time is reasonable.

I would try this instead of what's in line 132-3, or increase the wait time in 134. (Observation.recent_by_user is a recent scope I wrote for Observation that may be cached by the db, so... maybe faster?)

    last_obs = Observation.recent_by_user(User.current).last

Added those changes in #2270, will merge immediately
