Send pluralized wantBlock messages (#1016)

* don't unroll wantCids when sending wantBlock message in blockPresenceHandler

* workaround logging

* Fixes logformatting upraises for sequences.

* Applies upraises rule for setProperty of textmode for sequences.

* Replaces upraises with raises

* Removes redundant log in sendWantHave
