Previously, the type SpecWatchFilter in spec_test_runner was specified as a tuple, but it was later used with `push` and is actually an array with a first element that is guaranteed to be present, and of type TargetId[]. In Typescript 2.7, tuples will be fixed-length and this usage will fail. This changes the definition of SpecWatchFilter to an interface that extends Array<TargetId[] | string> and whose required '0' property is a TargetId[].

Looks like CI broke because of incorrect credentials. Not sure what is going on there. |

Change LGTM, though we need to get CI sorted out.
@jshcrowthe - what can we do to get travis's credentials sorted?

This is surprising that this works. Thanks for digging into it.

I found it when I was testing stricter tuples for Typescript 2.7. The new definition is basically equivalent to the old meaning of 'tuple' in Typescript.
