bug: cannot set equal aspect for log scale

[kinyatoride]

Steps to reproduce

import proplot as pplt

fig, ax = pplt.subplots()
ax.format(
    aspect='equal', 
    xscale='log', yscale='log',
)

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.set_aspect('equal')
ax.set_xscale('log')
ax.set_yscale('log')

This was fixed on master by 7cda3b23958f6f5896070b485d3db7210b3faec9, was due to another matplotlib dependency issue.
