Description:
Instance manager doesn't display log options correctly. This bug is non-deterministic.

Sample output from mysql client:

mysql> show instance options mysqld;

How to repeat:
issue "show instance options <instance_name>" for the instance wich has log enabled.
Several times as bug doesn't happen all the time.

Suggested fix:
Looks like wrong work with the memory, which is quite likely as this was recently changed.

The problem is not specific to the log files. I affects any option, for which the value is
not set. (E.g. --log, --core-file e.t.c).
