Calling `Font.findfont` results in `RecursionError` if no fonts are installed on the system

[ffishburn]

The fallback font for font-less systems is not quite working properly:

Steps to reproduce:

>>> from kiva.api import Font
>>> font = Font()
>>> font.findfont()

Looks like it may be due to an erroneous space in the font filename:

enable/kiva/fonttools/font_manager.py

Line 123 in fa865d8

path = os.path.join(data_dir, " Montserrat-Regular.ttf")
