Fix #268. Allow table actions when data is provided as dicts

[nickovs]

This PR fixes issue #268 to allow table actions when the table data is not taken from SQLAlchemy.

Currently each action URLs is formed by looking up the row record in SQLAlchemy, using the row's primary key and the provided model class. Not only does this mean that the URL creation fails for records that are not taken from SQLAlchemy (or something with the same API) but it also means that there is an additional database fetch for every action on every row.

The fix here makes the model parameter optional, even when actions are required. If no model is provided then any fields needed for building the URL are taken from the original row data. If a model class is provided then the functionality should be identical to before, complete with the extra database queries. This allows the record used to find URL arguments to be taken from a different model to that of the row data, as long as that table is indexed with the same primary key.

fixes #268

@greyli @PanderMusubi Any chance someone could approve the workflow, so that the build tests can run, and then look into merging this?

Looks good! Can you add some tests for this fix?

[nickovs]

@greyli I have added a variation of your test_render_table_with_actions() test case to perform all the same tests but with no database and the data passed as a list of dicts instead of Model instances.

I updated tests to reuse the existing test function (https://github.com/helloflask/bootstrap-flask/pull/284/commits/1b850645ccff349e0ffc0706778c6bbbe33fcebb).

Merged, thanks!
