Make all tests consistent + support for Ramda placeholder

Currently our support for ramda placeholder is limited. Almost all binary functions are lacking the support for it. We need to continually provide full support for it. Every binary function needs to have the following test in it’s test suite

  it('should support placeholder to specify "gaps"', function() {
    const trimStart = RA.trimStart(R.__);

    assert.strictEqual(trimStart('  abc'), 'abc');
  });

All other functions needs to have following curring test which tests the combination of params invocation:

  it('should curry', function() {
    assert.isTrue(RA.allEqualTo(1, [1, 1]));
    assert.isTrue(RA.allEqualTo(1)([1, 1]));
  });

As part of this, we should also refactor all tests to be consistent with gherkin style of testing. Here is an example PR which demonstrates what we want. I already invested tens of hours into this effort, but need help to rectify these things in the rest of our tests.
