removing old bower fix, have failing test to show issue

- test was updated to make copy of fixture since browserify-shim will remove files
finding package.json with mothership

- this means the first package.json upwards in the tree with a browserify-shim config will be used to apply configs
- that way the @fixPackage feature kicks in for the very first resolved file already
- all tests (including bower related ones) are now passing
reproducing invalid require issue with failing test
fixing invalid require statements

- after requiring our dependencies (which are valid) we shadow require
- this will cause if (typeof require!='undefined') to return false which
  is what we want
- fixes problems with libraries that contain requires that cannot be
  resolved
- problem similar to ember issue was reproduced and confirmed to be
  fixed
removing fix-packages

- not needed since the two problems were solved as follows
- finding root package done via mothership
- invalid requires fixed in the shimmed code
