bug fix an edge case for switching MIRI apertures

[mperrin]

Fix an edge case in some of the pixel scale checking code which happens when changing apertures.

Currently, can't switch from a SLIT type aperture back to a regular aperture. The following will fail:

miri = webbpsf.MIRI()
miri.set_position_from_aperture_name("MIRIM_SLIT")
miri.set_position_from_aperture_name('MIRIM_FULL')

With this PR, the above works without error.
