Change `LATEST_STABLE` with `VersionView.RELEASED_VERSION`
in tests checking default language configuration options.
Replace `LATEST_STABLE` with fixed version in `testDropKotlincOnVersionAutoAdvance`
as the test actually compares it with version from kotlinc.xml.
It being latest stable is not relevant.
By default the lastest stable Kotlin version is selected for module
when there is no explicit version in configuration. However, it is
the version previous to `LanguageVersion.LATEST_STABLE` during prerelease.
