Auto-complete in PMC works incorrectly with object methods

[alpaix]

Tab-completion on object property or method replaces the entire expression instead of just property/method name.

For example, following expression

$x = $context.try

after pressing Tab key will be replaced with

$x = TryResolvePackageAsset(

instead of

$x = $context.TryResolvePackageAsset(
