[MC-114953] Setting title times to negative values acts like /time ... clear

The bug

When you set the the title times all to negative value it acts like the /title ... clear command.

Expected behavior

The /title command should not allow negative time values.

How to reproduce

Set a subtitle
```
/title @a subtitle ["Subtitle"]
```
Set all title times to negative values
```
/title @a times -1 -1 -1
```
Display a title
```
/title @a title ["Title"]
```
→ You will notice that the subtitle is not shown

Can confirm for MC 1.12.1.

That issue apparently has been fixed in some 1.13 snapshot.

It now just errors out:

Couldn't execute command for miwob: title @a times 1 1 -1
