Wrong error message if git is unvailable

[carlhoerberg]

If the git command is unavailable I get:

Locked version 0.1.1 for PKG was not found in git: https://gitlab.com/X/PKG.git.

Instead of expected:

Error missing git command line tool. Please install Git first!

I guess

shards/src/resolvers/git.cr

Line 421 in 02055f9

raise Error.new("Error missing git command line tool. Please install Git first!")

is swallowed here:

shards/src/molinillo_solver.cr

Line 33 in 02055f9

rescue ex : Shards::Error

Shards 0.17.2 prints "Failed to clone" but doesn't say anything about why it failed (i.e. that git is not available).
