Expected behavior:
When running a benchmark with a warmup period of 30 seconds and an erroneous customProperty in the solver config, the benchmark should fail immediately and not spend the 30 seconds on warmup

Observed behavior:
The expected IllegalArgumentException is raised after 30 seconds of warmup time

How to reproduce:

• Configure warmUpSecondsSpentLimit of 30 seconds in plannerBenchmark
• Configure a solver config with a custom phase and custom property value "NONEXISTING" (in our case it was an invalid Enum value)
• Launch the benchmark
• Exception is raised too late in `DefaultPlannerBenchmark.benchmarkEnded()`
