Improve assertion description for hasValidGettersAndSettersExcluding("…")

[netsrotr]

Suggestion

Change the assertion description returned on fail for assertThat(BeanToTest.class, hasValidGettersAndSettersExcluding("dontTestPropertyWithThisName")) to list the expected properties, not the already known (and yet provided) excluded properties list.

We use assertions of this kind very often, because of many read-only properties:
assertThat(BeanToTest.class, hasValidGettersAndSettersExcluding("dontTestPropertyWithThisName"))
The current behavior: if assertion matcher fail, it list the the already known (and yet provided) excluded properties list within the fail-description.

This information is redundant and does not really help to exactly point/describe the issue: one or more properties have no valid setters/getters, but which of the remaining at the class under test?
Expected behavior: it should instead list the properties that are found by the "magic" JavaBean (with the excluded properties subtracted). This information would really help test developers to track down to the point.
