RandomPlayerAI wrong teamsize assumption

[1iminal]

Running a battle versus a RandomPlayerAI with a team of size 1 causes an error:

(node:5460) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'condition' of undefined

At /sim/tools/random-player-ai.ts#L102 RandomPlayerAI assumes teamsize is at least 2, which may be not necessarily true.

This can be fixed by checking the teamsize before running the status check on allies.

let hasAlly = false;
if(pokemon.length>1){
  hasAlly = !pokemon[i ^ 1].condition.endsWith(` fnt`);
}

Do you want to PR that or should I?

Also @scheibo do you have any opinions on this?

I can do a PR if noone is against it

Sorry, missed this bug (though apparently I had seen the PR). Thank you for finding and fixing.
