fix: isHashID matches for hyphenated application names

Fixes `isHashID` checks for hyphenated application names

When a user calls bd init inside an application that has a "-" for
example my-first-application without any options than ids will follow a
pattern of my-first-application-{ID}. When using SplitN on the "-"
separator it would result in the split parts returning as [my,
first-application-{ID}] which is incorrectly pulling out the {ID}
resulting in the `isHashID` returning false when it could be a hash id.

Instead of using SplitN, this changes to find the last index of the
separator resulting in the suffix becoming the actual {ID}.
