fdo#44715 RTF import: reset styles in tables on RTF_PARD

Commit 4a507f73 added an exception to
RTF_PARD (reset paragraph properties) handling: when we're inside a
table, it should not reset the fact that we're inside a table (which is
a paragraph property).

However, instead of just re-adding that property, it disabled resetting
for all properties, and we had a growing list of exceptions since then.
The next thing to add there would be the paragraph attributes, which
contains the style information. Instead of growing that ad-hoc list,
reset everything again and just re-add the "in table" SPRM.

This makes the second and later paragraphs in the A1 cell of the bugdoc
have proper font size.
