rspec fails on XActivatePowerMode

[mralexgray]

rspec is choking on (the valid) Image URL https://camo.githubusercontent.com/a25916ccc96abf4f949ae55a3fc8b0108ac578a8/687474703a2f2f3764396f30782e636f6d312e7a302e676c622e636c6f7564646e2e636f6d2f584163746976617465506f7765724d6f6465707265766965772e676966 simply because it doesn't "end with" an image extension as defied in the spec.
