[flow] unused suppression in beta 6

[oonsamyi]

Problem description

I have the following error related to flow:

Error: node_modules/material-ui/Card/Card.js.flow:21
 21: // $FlowFixMe - invalid error? claims raised prop is missing
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error suppressing comment. Unused suppression

Steps to reproduce

1. Install version beta.6.
2. Enter the command flow.

Versions

• Material-UI: 1.0.0-beta.6,
• Flow-bin: 0.52.0

You need to suppress this comment:

@oliviertassinari that's not the issue here. Flow checks when a suppression comment exists that's unnecessary. What the error is saying is that it found a suppression comment ($FlowFixMe), but it's above a line that doesn't actually throw an error in the first place.

Could that be a flow missmatch version issue or we can simply remove the comment?

Flow may have fixed a bug, which means the suppression is now unnecessary, so we just remove it.

Regardless, this will probably get fixed as #7788 is fixed (in progress today).
