Correct order of arguments to a regex call in safe_xlsx_sheet_title

[marisn]

PR #490 had non-functional tests and thus an invalid order of arguments to re.sub was unnoticed.
This PR corrects the call, adds tests + applies same treatment to sheet names also when saving a databook.

Fixes #489

A couple of suggestions

[claudep]

Thanks!

Hi is there a bugfix release planned for this change? Maybe version 3.1.1? The current latest (3.1.0) breaks exporting dataset in XLSX because of the sheet name being crushed with -.

[hugovk]

Hi, yes, I think it's time for a new release.

Notable changes since 3.1.0 are this, #508 (add support for Python 3.10) (edit: 3.10 was added in #504 and already released) and #513 (drop support for EOL Python 3.6):

v3.1.0...master

@claudep Do you think dropping 3.6 warrants a major bump (Tablib 4.0.0) or minor (Tablib 3.2.0)?

I generally go for major bumps when dropping Python versions, but I don't really mind as we're using python_requires so pip should handle things nicely.

[hugovk]

(We called the 2.7 and 3.5 drops breaking changes and bumped to 1.0.0 and 3.0.0 respectively.)

[casimir]

Just a little more context, I'm still stuck with python 3.6 for the few months to come. That's why I was talking about a bugfix release like 3.1.1 (I assumed semver without checking the project policy though).
On the other side I understand very well the burden of such process and I would also understand that you only cut a new release from the current tip.

[claudep]

@hugovk 3.2.0 would be fine for me.

@casimir In your specific situation, I would temporary install tablib from a specific git commit (pip supports that) until you can upgrade to Python 3.7+.

[casimir]

I'll stick with the 3.0.0 while I'm stuck with Python 3.6. Just my 2 cents but I would at least yank the 3.1.0 on pypi as this is a really disruptive bug.

Thanks for the quick response. And also thanks for reviving this nifty project.

[hugovk]

3.2.0 released!

You can tell pip to ignore the Python version check with --ignore-requires-python and hope for the best:

$ python3.6 -m pip install tablib==3.2.0
