test: full coverage SlashEscrowFactory + SlashEscrow (#1403)

**Motivation:**

We want to ensure we have full coverage unit tests for
`SlashEscrowFactory` and `SlashEscrow` in preparation for audits.

**Modifications:**

- Adds checks for all view methods.

**Result:**

Brings coverage up to 100% for all branches/fns/etc.
