fix: comparison between min_sdk_version

Added test demonstrates the error case. The bug was that java modules'
ShouldSupportSdkVersion() converts min_sdk_version into effective
version before comparison, which discards "preview" version into
"future" version. That caused a weird case like rejecting with error
"should support "S"" even when it is set to "S".

Bug: n/a
Test: m nothing
