Seems like I have found a workaround for this issue. Put following lines
to you apt.conf:

Aptitude::ProblemResolver::Break-Hold-Level 50000;
Aptitude::ProblemResolver::Keep-All-Level 40000;
Aptitude::ProblemResolver::Remove-Level 20000;
Aptitude::ProblemResolver::Non-Default-Level 15000;

The default levels and explanation can be found in documentation which
can be installed by apt-get install aptitude-doc-en.

PS: looks like there is no difference in costs between removing the
package which was asked to be upgraded and removing of some other
package. So there is a tradeoff in setting Remove-Level vs other levels.
I found the value most appropriate for me.
