fix: Throw error when `getArrayLength` receives an empty array

[jooy2]

I didn't think of a handling case for empty arrays in my previous PR (#118), I'm a super idiot!

I apologize for the hassle with this ongoing fix. This situation happens frequently and i hope this fix gets reviewed quickly.

This PR resolved the issue in the reproduction below:

How to Reproduce:

For example, suppose you have the following situation:

<Console
    logs={[
      {
        method: 'log',
        id: 'id',
        data: [[], {}, [{}]],
      },
    ]}
/>

If so, you should see the following error in the console below:

TypeError: Cannot read properties of undefined (reading 'toString')

      38 |     return array.length
      39 |   } else {
    > 40 |     const remaining = parseInt(
      41 |       array[array.length - 1].toString().split(REMAINING_KEY)[1]
      42 |     )
      43 |
