Join Wiring Editor tests cases improve test speed and reliability

Before this patch, the wiring editor tests cases are splited into
several test cases, making selenium to start and close the browser too
often. Moreover, some tests were grouped in a way that they cannot make
use of a different feature set. For example, some tests require search
indexes while others not, but due those tests using search indexes, all
the tests on the test case were forced to use search indexes, causing a
big time penality.
