Fix for Email counts not working

[thartl]

Email counts were not incrementing for me and a couple small code edits made it work.
I thought I'd share in case this is a valid fix. I will fork and submit a pull request.

Plugin version - 1.2.0

Current Behavior

With the plugin set to use SharedCount.com as Count Source, email shares were not incrementing.

Possible Solution

In class-shared-counts-core.php:

1. On Line 125, changed the comparison operator from === to !==
2. On Line 127, changed post-increment ($count++) to pre-increment (++$count)
