fix: prevent preparing chart for disabled releases (#1210)

* fix: prevent preparing chart for disabled releases

Previously, PrepareCharts does not filter any releases whose condition
is disabled with no selectors.

Prevent following things from
- using any unnecessary computing resources for disabled charts
- throwing any error from wrong configurations for disabled charts

* fix: working for integration test about list and build

Some tests require that PrepareCharts without any selector
may not add any labels on the release.

make markExcludedReleases do not add any label without any selectors

* fix: prevent resolved chart version loss

State loss the resolved chart version info from st.Releases
when st.GetSelectedReleases() be called

update st.Releases after st.GetSelectedReleases() in prepareCharts

* fix: preserve resolved version from resolveDeps

In PrepareCharts, the version, resolved from resolveDeps,
is removed after invoking GetSelectedReleases.

Do updateDeps at the first before GetSelectedReleases call
