Fix REPL issues when processed JS modules which are transitive deps of

a require failed to load.

it seems it's possible for a source to have stale :provides &
:requires. This doesn't seem to have been observed in builds because
Closure uses the information in the compiled sources, and under
:none we compute dep.js in one pass.

This fixes the immediate REPL issue with processed JS modules by simply
using the compiled source to determine :provides / :requires
