history() doesn't work

[rcerven]

import podman

pclient = podman.Client()

img = pclient.images.get('6c0fc7ee13e0')

for his in img.history():
print(his)

fails with :
Traceback (most recent call last):
File "test.py", line 11, in
for his in img.history():
TypeError: 'list' object is not callable

problem is that when Image object is created, it defines attribute history and sets it to '[]'

which overrides history() method
