Enforce at least two methods arguments for composition methods

Giving one argument to composition methods like _.flow and _.compose is useless, as _.flow(fn)(x) is the same as calling fn(x).

Fail

import _, {flow} from 'lodash/fp';

flow(fn)(x);
_.flow(fn)(x);

Pass

import _, {flow} from 'lodash/fp';

flow(fn1, fn2)(x);
_.flow(fn1, fn2)(x);
