templateparserjobtest suffers 3 failures in test_replyHtml() at lines

QVERIFY(parser->d->mOtp->htmlContent().isEmpty());
QVERIFY(!parser->d->mOtp->plainTextContent().isEmpty());

I think these lines were added accidentally.

• If I understand the git history, they were added in revision a13359849ef0, "Merge branch 'Applications/19.04'", but they don't exist on the 19.04 branch or the previous master revision.
• The first line verifies that htmlContent is empty, but later the test checks for expected HTML content.
• test_replyHtml() has similar structure to test_replyPlain(), test_forwardplain(), and test_forwardHtml(), which do not have similar tests.

This patch deletes the lines.
