Fixed
* save/restore internal order_id

Update
* up requirements for exchanges-wrapper to 1.2.7-3

Update
* Refusal to use PROFIT_REVERSE parameter.
Valid for Reverse cycle. For a small deposit, the cycle income can be equal to the minimum order size step.
If you divide it into parts to increase the deposit and make a profit, as a result of rounding the deposit amount does
not increase, which negatively affects the ability of the strategy to complete the reverse cycle.
Instead, all cycle profits are allocated either to increase the deposit (for an odd cycle number)
or to accumulate profits (for an even cycle number)

Fixed
* For analytic export replace Bitfinex mapping from "IOTA to MIOTA" to "IOT to MIOTA"
* Migration transition solution cleared for saved_state from 1.2.6 - > 1.2.7
* lgtm [py/unused-import]

Update
* get_min_buy_amount()
