This test just went from Pass -> RuntimeError on unittest-asserts-release-win-arm64, but because of an expectation failure and not a crash.

  Expected: equals [15, 16, 28, 30, 31, 36] unordered

[stable] [vm/service] Fix JSON array parsing bug that causes seg fault
09b3b74 
Changed the definition of `end` to point 1 past the end of the element,
rather than the end of the element, which avoids the need for buggy
look-ahead style lookups.

I think this must have been a long standing bug, and we just never sent
empty JSON arrays to the service until now, because I didn't change this
logic when I refactored it.

TEST=Added Service_ParseJSONArray
