You are not the only one. IND support people are also confused

"Life in the UK Test
If you pass this test you will not need to produce additional proof of your knowledge of English. This is because to pass the test you will need to be competent in English."
I guess your dates are pretty close and can
go in your favour if you just take the test now which only consists of 3
chapters and later on they will add more chapters. Then off course we are
not making the judgement and if you ask IND
they will be as confused as us because I never got a straight answer from them.
IMO - Taking test will fulfils the requirement that IND has, so if you are eligible
to apply before 2nd April, I say take the current test because by then you
already placed your application in the home office. I can also conclude from their explanantion above (in bold) taht if you take test once it is valid for ever.
