(Bug) Minted: 2nd tier has incorrect rate

[dennis00010011b]

Steps:

1. Create crowdsale, Minted,no whitelist, 2 tiers, decimals =18:

   - 1st tier: rate =100,  supply=100, minCap =0
   - 2nd tier: rate =200, supply=100, minCap =0 

2. Wait until 2nd tier starts and buy 10 tokens as an owner (I have waited until 10 minutes after 2nd tier start before the purchase for exclude a propagation time). Check Eth amount for transaction (in metamask window)
3. Observe contribution page after transaction

Expected result:

• transaction amount should be: value/rate=10/200=0.05 Eth

Actual result:

• transaction amount is 0.100 Eth
• owners balance is 20 tokens after transaction

Issue is not reproducible for non-owner account
