prevent panic when parsing incomplete multi-expr (|) matches (#15230)
Fixes #14971, fixes #15229

# User-Facing Changes

Fixes a panic when variable data is accessed after invalid usage of the
`|` separator, which made it impossible to type certain match arms:

```nushell
> match $in { 1 |
Error:   x Main thread panicked.
  |-> at crates/nu-protocol/src/engine/state_delta.rs💯14
  `-> internal error: missing required scope frame
```

# Description

Removes duplicative calls to `exit_scope` from an inner loop when `|`
parse errors are encountered. The outer loop creates and exits scopes
for each match arm.

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
