[ticket/10933] Initialize template context when template is constructed.

There is no apparent reason for either initializing or clearing
the context in set_style/set_custom_style.

Initially the initialization there was added in
0501640d5db158a010741e27803191ab469834c4, for reasons that
presently I do not see.

This permits making context property back private.
