Fix an incompatibility with hamcrest 2.2 (#31395)

This test asserts on the message of an AssertionError thrown by a
failing hamcrest assertion. The message changes in the latest versions
of hamcrest.

```
1) testBadCoderIsNotDeterministic(org.apache.beam.sdk.testing.CoderPropertiesTest)
java.lang.AssertionError:
