Promise launcher compares current slapgrid version with an old version
number to determine if some feature is supported or if it should use a
legacy workaround. But the comparison was a simple lexicographic order
string comparison, and now that we incremented from 1.9.3 to 1.10.0 it
wrongly compared the versions. Fix it with pkg_resources.parse_version.
