AbstractVerifierTest: adapt tests to reflect that tabs are preserved by the DN parser

Recently in
53f06c0d1dd4c7b48c965a8c6270d6acb12161ca
I changed the tests to reflect the fact that tabs and newlines were
discarded.

I must have made some mistake verifying the change, as tabs seem preserved.

Changing the assertion for tabs.
