Watch mode rebuilds multiple times - resulting in the smallest lib taking 15s to be updated

[vpiskunov]

Using relative-deps with NestJS - we have a very small lib and even in such case, it takes 7s per rebuild and runs it twice (maybe I've seen it run 3 times but might well be wrong on this detail).

It's a TS project so just uses tsc to build - nothing fancy that I can see. Any pointers of how this could be resolved?

And great work on the relative-deps @mweststrate !
