#1313 Missing assertion message in assertEquals with delta not detected

[Robert Whitebit]

A missing assertion message in the junit method assertEquals with delta [assertEquals(double, double, double)] won't be detected.

Since pmd can't always detect the types of the arguments, it can't be solved 100%.
assertEquals(double, double, double) ?= assertEquals(String, double, double)

I already fixed it. PR is coming soon.
