Stop Task Failure in client_func_test.go

* /home/travis/gopath/src/github.com/intelsdi- x/snap/mgmt/rest/client/client_func_test.go
Line 351: - runtime error: invalid memory address or nil pointer dereference goroutine 11 [running]: github.com/intelsdi-x/snap/mgmt/rest/client.TestSnapClient.func6.3.4()
/home/travis/gopath/src/github.com/intelsdi- x/snap/mgmt/rest/client/client_func_test.go:351 +0x237

351: So(t2.Err.Error(), ShouldEqual, "error 0: Task is already stopped. ")

Now moved to line 353 after step 1 was changed

 * /home/travis/gopath/src/github.com/intelsdi-x/snap/mgmt/rest/client/client_func_test.go 
  Line 353:
  Expected '<nil>' to NOT be nil (but it was)!

Things to fix:

• Add tests if there even is an error e.g So(t2.Err, ShouldNotBeNil)
• What is causing the timing issue

Closing due to age of the bug and lack of context to move forward with a fix.
