Template tag errors masked if including based on context variable name

Description

I have a template tag that raises a RuntimeError. Normally, this gets displayed properly to the user, but I have found a case where it doesn't. If I {% include includefilename %} where includefilename is a context variable pointing to a template, then template tag errors are masked. If I do the very same include, but specify the template name directly without using the context variable, things work properly.

I have attached a barebones demo of the problem. To see the demo, runserver and check the template files. You can uncomment my includes in index.html to see the problem.

Patch looks good,but needs tests.

..and tests would in turn require rewriting a chunk of template tests, because currently they test for things only with "TEMPLATE_DEBUG=False".

I'll try to finish that tomorrow.

Fixed #14046 -- Made {% include %} behave the same, regardless of whether the template included is named by variable or constant string. Thanks to defcube for the report, and George Karpenkov for the draft patch.
