If I don't contain [hash] or [chunkhash] on output bundle file name,
this function(removeFileNameHash) return / include in front of result
for example,
parameters
buildFolder: /resources/app/dist
fileName: /resources/app/dist/mobile-cs-center-v2/bundle.js
return value
expected: mobile-cs-center-v2/bundle.js
result: /mobile-cs-center-v2/bundle.js
It's effect on printFileSizesAfterBuild function to print difference file size.
