Issue 627 (#746)

* added test to fs.readlink.spec.js

* added test for fs.write() to try and write a file opened without the O_WRITE flag

* added test to fs.write() that attempts to write with a buffer that is too small

* added a test to fs.write() to try and write to a file that doesn't exist

* added more specific summary of test for writing to buffer when length is too long, check the type of error that a test returns

* Adjusted the message on line 69 to be more clear
