fix typo in test

[remicollet]

Without this, using PHPUnit 5.4.4

There was 1 failure:

1) EasyMock\Test\EasyMockTest::should_allow_to_spy_method_calls
Failed asserting that 'Expectation failed for method name is equal to <string:foo> when invoked at least once.
Expected invocation at least once but it never occurred.
' contains "Expected invocation at least once but it never occured".

Thanks! Tests are run against the latest versions of the dependencies as well as the lowest (allowed by Composer), which explains why the build fails.

Could you simply remove the word ("occurred") from the assertion? That way it should be good to go for all versions.

Thanks again

I have removed the trailing "red", (so both occured and occurred should work)
