FileClient tests fail locally

Not sure if it is related to my setup

    √ should be able to write and read files using URI scheme file:/// with no Content-Type

    2) should be able to write and read files using URI scheme file:// with Content-Type text/plain

The test also fail for me sometimes (I am currently using a Mac), so this is a general problem :/ I will try to come up with a fix for the issue, sorry for the inconvenience this causes :/
