no-obscure-array-access fix is incorrect with modifier usage

[Alonski]

Failing PR:
#2923

This code:

<Button @onClick={{fn this.myFunc @row.0.sha256}}>
  Button
</Button>

Is expected to be fixed to:

<Button @onClick={{fn this.myFunc (get @row "0.sha256")}}>
  Button
</Button>

But instead is fixed to:

<Button @onClick={{fn @row "0.sha256"}}>
  Button
</Button>

Which is incorrect. The function this.myFunc is now gone.
