fix convertInchesToCentimeters function

[paolomangiadev]

There is currently a method called convertInchesToCentimeters that lives in /lib/convertInchesToCentimeters.js.
It is incomplete and needs to be fixed!

Description:
A number indicating a measurement in inches is passed to the method and the return is the same measurement converted in centimeters. e.g. 7in => 17.78003556007112cm

Acceptance Criteria:

1. Running yarn test convertInchesToCentimeters results in tests passing.
2. You have written a skeleton method for someone else to work on.
3. You have written tests surrounding your skeleton method.
4. Running yarn lint does not print any errors to the console!
5. Optional:

• write one or two more tests surrounding the method you are solving to account for potential edge cases.
• add the option of rounding the resulting measurement (centimeters).

Please include the skeleton of a new method + an accompanying test for someone else to work on at the time of creating a pull request! A pull request will most likely be denied if it does not contain a skeleton method for someone else to work on! For more information, please read the Contributing Guide.

Thank you so much for your contribution!

Was just taking a look at this and @paolomangiadev , it looks like the initial tests for this method pass no matter what.

The expect in "Should return converted inches to centimeters" always evaluates to true. Something to keep in mind @lmauromb

Marking as in progress. @lmauromb - take a look at those tests while you're digging around, thanks!!
