Collection count can be converted to size

Reports calls to Collection<T>.count().

This function call can be replaced with .size.

.size form ensures that the operation is O(1) and won't allocate extra objects, whereas count() could be confused with Iterable<T>.count(), which is O(n) and allocating.

Example:

fun foo() {
    var list = listOf(1,2,3)
    list.count() // replaceable 'count()'
}

After the quick-fix is applied:

fun foo() {
    var list = listOf(1,2,3)
    list.size
}
