Change subject: Bug 50603: Handle |{{echo|{{!}} Foo}}

Bug 50603: Handle |{{echo|{{!}} Foo}}
Add a DOM post-processor pass that fixes the handling of this test case:
{|
|{{echo|{{!}} Foo}}
|}
The first td is removed and the appropriate adjustments to the
transclusion-generated td are performed (DSR adjustment, data-mw updates).
Also add two test cases to verify wt2html, wt2wt and html2wt modes.
This is the first (and easier) part of bug 50603, the second part is still
TODO.
