#24685: EngineHandler doesn't raise exception when duplicate aliases are
registered

---------------------------------+--------------------
The `django.template.utils.EngineHandler` has a check to raise
`ImproperlyConfigured` if multiple engines are specified with the same
alias:
https://github.com/django/django/blob/master/django/template/utils.py#L72
This won't ever raise an error, though, because configuration is stored in
an `OrderedDict`. Duplicate aliases simply overwrite previous ones.
Curtis ran into this problem when using settings like this without the
`NAME` option:
{{{
TEMPLATES = [
{
'BACKEND': 'knights.django.KnightsTemplater',
...
},
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
...
},
]
}}}
