bug in ZPT engine with tal:on-error and i18n:translate

[Godefroid Chapelle]

The content inserted by tal:on-error in an element is not translated by the i18n machinery.

How to demonstrate :

add two files to test suite of TAL

> input/test37.html

> <span i18n:translate="" tal:content="xxx" tal:on-error="string:No xxx" />
> <span i18n:translate="" tal:content="string:xxx" />

> output/test37.html

> <span>NO XXX</span>
> <span>XXX</span>

the supplementary test fails; the output produced is :

> <span>No xxx</span>
> <span>XXX</span>

For those that do not know the test suite; the dummy translation service used actually transforms strings to uppercase.
