remove duplicate tests

As tests are claimed as duplicates, you run these tests and should see the same result numbers at least.

This is not true and assumption is wrong.
Tests should be restored as they test different usecases on different images.

1. I removed tests with bardet.detectMulti(src, corners);
   The func detectMulti() just call detect() from PIMPL:
   
   I left tests with bardet.detectAndDecodeWithType(src, decoded_info, decoded_type, corners);
   The func detectAndDecodeWithType() call detect() from PIMPL:
   
   Therefore, the detect() function continues to be tested.
2. I'm not sure why we need to run the detectMulti() function in our "perf" tests. It is already being tested in BarcodeDetector_main.interface (test_barcode.cpp).

There are different image inputs (single/multi) for these tests.
No need to exclude or combine them.

@opencv-alalek, ok, I returned all tests, but I still think that two tests can be removed, but this is not a big problem ^_^
