[Bitbucket Cloud] Test-Mockup encoding / exec global

[sti0]

This forces the mockup encoding to utf-8. Rest client expects a utf-8 encoding:

atlassian-python-api/atlassian/rest_client.py

Line 224 in 5028c00

response.encoding = "utf-8"

Prior Python 3.9: without encoding files are read with system default codepage, e.g. windows = cp1252.

E.g. Python 3.8

encoding is the name of the encoding used to decode or encode the file. This should only be used in text mode. The default encoding is platform dependent (whatever locale.getpreferredencoding() returns), but any text encoding supported by Python can be used. See the codecs module for the list of supported encodings.

Additionaly the exec global "null": None is added, because BB cloud api may return the value null instead of None.

For which response is the "null" needed?

[sti0]

I simply dumped the json from the pull request response for unit tests and some attributes are null.
At the docs they can be null:

Ok, in my previous dumps there wasn't a null.
