[Pkg-rust-maintainers] Bug#1051615: rust-minijinja: Uninstallable dependencies

[Jeremy Bícha]

Control: reopen -1

librust-mininija-dev is still uninstallable because it has Depends:
librust-v-htmlescape-0.15+default-dev and
librust-indexmap-1+default-dev but neither of those exist in Debian.

This was detected by Britney and piuparts lists the specific missing
dependencies.

Thank you,
