fixes for issues 196 and 197

Note

This is a somewhat staged pull request. I (@mfranke93) am both the pull-requestee and owner of the fork, and the reviewer. The purpose is to showcase how to submit a pull request to this repository, and what review steps might occur.

Since I cannot be assigned as an actual reviewer on my own PR, I will have to put the review requirements as ordinary messages.

Actual Message

• Updates deploy.sh to check for empty version strings that would lead to an error with docker build (UniStuttgart-VISUS/damast#196). In this case, a detailed error message is shown, suggesting to fetch upstream tags.
• Updates README.md to include a note on fetching upstream tags in forked repositories for deploy.sh to work (UniStuttgart-VISUS/damast#196).
• Fixes docs/postgres/Makefile and, by extension, make prod to build all dependencies first (UniStuttgart-VISUS/damast#197).

Please change the formulation in the CHANGELOG: Split up the sentence regarding issue #196, and clarify "(forks)" better.
