Title: Add null check on subscription blocks

`env.Content.subscriptionBlocks` is nullable and needs to be checked, otherwise we will get this exception:

```nodejs
error: TypeError: /home/thont/Desktop/habitrpg/views/shared/modals/members.jade:78
76| .panel-body
77| .form-group
> 78| each block in env.Content.subscriptionBlocks
79| .radio
80| label
81| input(type="radio", name="subRadio", value="#{block.months}", ng-model='gift.subscription.months')

Cannot read property 'length' of undefined
