HeadOf.java:35-39: Remove this class and replace it...

[0pdd]

The puzzle 1242-3e1cce64 from #1242 has to be resolved:

cactoos/src/main/java/org/cactoos/collection/HeadOf.java

Lines 35 to 39 in 2a62719

	* @todo #1242:30min Remove this class and replace it everywhere
	* it was needed by the appropriate usage of HeadOf from iterable
	* (composed with ListOf or SetOf in case a copy is needed)
	* or any other relevant concrete collection implementation.
	* See #1242 for the rationale about this.

The puzzle was created by Victor Noël on 09-Feb-20.

Estimate: 30 minutes, role: DEV.
