OutputConditionsAlg: Adjust output messages after using GaudiProperty instead of plain type
The change I made in !47235 (merged) had an undesired side effect: Using GaudiProperty
objects as parameter to MsgStream
prints also the name of the property. This failed the log-diff'ing unit test LArConditionsTestWriteNoReg
in today's nightly.
Fixing by explicitly using prop.value()
.
