App fails to build master list of issues if there are less than 2 issues in /issues

[isidorosp]

There's a bug in index.tsx due to the fact that it expects to find multiple issues within /issues and thus return an array to map over. If there are no issues, or only one, then this fails.

• Show something special if no issues at all exist
• Fix the method so that 1 issue doesn't fail
