New issue 789: PhasePlot save missing string
https://bitbucket.org/yt_analysis/yt/issue/789/phaseplot-save-missing-string

gsiisg:

If I save the phase plot in another directory with:

pplot = PhasePlot(dd, "Density", "Temperature", ["Electron_Fraction"],
                 weight_field=None)

pplot.save('frames/')

the file name is "frames/_2d-Profile_Density_Temperature_Electron_Fraction.png"

if I just use

pplot.save() it will include the pf string as 
"HD1200_2d-Profile_Density_Temperature_Electron_Fraction.png"
correctly.

So by specifying the folder it replaces the pf string.  ProjectionPlot does not have the same issue.  Annoying bug, but not critical.
