Throttling Switchers does not work when using strategy inputs

[petruki]

Describe the bug
This is a legacy bug that prevent throttle to proper cache results when Switchers have input strategy.

To Reproduce
Define a Switcher using the following:

final Switcher feature = getSwitcher(MY_SWITCHER)
	.checkValue("user_1")
	.throttle(1000);

This settings should make every call from the SDK to verify cached results and run the API call in the background.
However, when using strategies check..., the cache fails to identify the records and proceed with remote call.

Expected behavior
Throttle API calls handling the cache when strategy is defined
