tests: print enum type members more like object type members

Commit 93bda4dd461 changed the internal representation of enum type
members from str to QAPISchemaMember, but we still print only a
string.  Has been good enough, as the name is the member's only
attribute of interest, but that's about to change.  To prepare, print
them more like object type members.
