"Link to current turn" sharing option has no effect

[carloscbz]

When sharing a replay, the URL does not change when selecting the option "Link to current turn", so the replay always starts from the beggining.

I tested it with Firefox 61 and Chrome 67. Tested cases:

• Copying the URL manually
• Copying the URL with the "Copy" button
• Clicking the Reddit share button
• Clicking the Twitter share button

In all cases the URL is the same and the replay does not start at selected turn.

Thanks for the report! This duplicates HearthSim/HSReplay.net#857, but thanks for the test cases!
