forecaster.py refers to deleted pickle files about prophet

@AashishTiwari Since they are platform dependent, these files are created when you install the fbprophet package. It looks like your install procedure didn't correctly create and place the model files. I think this part of our generic Windows 10 issue. We're in the process of getting a Windows machine to debug.

See #74.
The issue here seems to be that Python was started from the source directory python/, and so when fbprophet was imported instead of importing it from site-packages, it imported it from the current directory. This is fixed just by starting Python in a directory that does not contain fbprophet subdirectory. @AashishTiwari does that fix it for you?

Hey @bletham, Thanks for the suggestion and pointer to the other issue.
Dropping the editable mode while installing from source, fixed the issue for me.
