Birunthan Mohanathas 30524a6fbd Tweak 'Cache not found' message (#54)
Previously the message was like this:

```
Cache not found for input keys: ["xxx",""]
```

Note the empty entry at the end because `String.prototype.split` results
in an array with one empty string if there was nothing to split.

Now it looks like:

```
Cache not found for input keys: xxx
```
