fix(1358): add trailing zero when mask="separator.1" and leadZero="true"

[nathanielbuck]

Currently, no trailing zero is added when mask="separator.1" and leadZero="true" and input loses focus. This change adds the trailing zero in that case.

What is the current behavior?

When mask="separator.1" and leadZero="true", the input's value doesn't change when there is no decimal and the input loses focus. So, if 1 is entered in this case, the value remains 1 but the desired result is that the value would be changed to 1.0.

Issue Number: JsDaddy#1358

What is the new behavior?

When 1 is entered and the input loses focus, the value is replaced with 1.0
