Fix incorrect filepath from url, fixes #140

[s0ph1e]

Bug

getFilepathFromUrl returns path which contains trailing slash, for example /path/to/file/
if html-file has no extension - filename generator adds default filename (index.html) to received path, so filepath will be /path/to/file/index.html

Bug #140 reproduces if there are both email and trailing slash in url (f.e. /users/test@example.com/):

• email contains .com which is recognized as extension -> so default filename is NOT added to filepath and it remains as in url (/users/test@example.com/)
• FS tries to save file /users/test@example.com/ but it thinks that test@example.com should be directory because of trailing slash and tries to open it => saving to FS fails

Solution

getFilepathFromUrl should return correct filepath from url, without trailing slash

I tried the code changes you submitted locally and the error no longer occurs :) Once the code is merged in, I'll update my node module. Thanks for fixing.
