fix type hierarchy regression since VS Code 1.75.1

[CsCherrYY]

Open a Type Hierarchy in a given type will shows an error editor. But it works in VS Code 1.75.0 and before.

Root cause:

• There was a bug in TypeHierarchyModel.location(), we should use Uri.parse() instead of Uri.file() since we're using jdt scheme to express class types. Before VS Code 1.75.1, this method will not be called since we bind correct Uri in the tree item command:

  vscode-java/src/typeHierarchy/model.ts

  Lines 122 to 128 in a5a061f

  	treeItem.command = (element.uri) ? {
  	command: 'vscode.open',
  	title: 'Open Type Definition Location',
  	arguments: [
  	vscode.Uri.parse(element.uri), <vscode.TextDocumentShowOptions>{ selection: element.selectionRange }
  	]
  	} : undefined;

• VS Code 1.75.1 introduces a change to auto reveal the item when it's selected, see: microsoft/vscode@a89b0e9, in this process, TypeHierarchyModel.location() will be called, causing this bug.
