Fix incremental compilation in some compiler plugins

If compiler plugin removes source files between rounds of incremental
compilation, it may result into incorrect state of stubs. But rebuilding
stubs may require services available in UI mode only and cause
compiler failure.
This commit contains work-around allowing to avoid incorrect state of
stubs.
