IsFinite() always returns false if the Dec is finite.

[SpicyLemon]

Summary of Bug

The new Dec.IsFinite() function returns false if the Dec is finite, and true otherwise.

cosmos-sdk/x/group/internal/math/dec.go

Lines 49 to 51 in 2c0d445

	func (x Dec) IsFinite() bool {
	return x.dec.Form != apd.Finite
	}

func (x Dec) IsFinite() bool {
	return x.dec.Form != apd.Finite
}

Luckily, that function isn't used anywhere and it's in an internal directory, so it's not even in use by consumers of the SDK.

Version

Steps to Reproduce

Look at the code linked above.

Whoops, forgot to clean that up (as we don't need it). This can just be removed.
