fixed problem with recursive dependencies

Now we have getListSwirlFileProvide that given a list of deps it returns
a list of swirlFiles which are necessary to satisfy them (without
recursion, it only satisfy the given deps).

While getListSwirlFilesDependentStatic given a swirl file it return
a list of swirlFiles which are necessary to resolve all the deps of the
given swirlFile plus all the deps which are added by the various
swirlFiles (recursive dependencies)
