autoformat issue: `=>` in a function call aligned with `=>` in a different function call

[lelutin]

The autoformat function is apparently going beyond the boundaries of the hash inside the function call and aligns things across different function calls. This is wrong and it shouldn't happen.

simplest reproducer:

longer_function_name('some value', 'some other value', { 'blah' => 'moo' })      
ensure_resource('file', '/something', { 'ensure' => 'file' }) 

with the cursor placed on the => (or anywhere inside that hash), press gqi} to trigger autoalignment.

The result is the following:

longer_function_name('some value', 'some other value', { 'blah' => 'moo' })      
ensure_resource('file', '/something', { 'ensure'                => 'file' })

the autoformat function should stop processing at the {} boundaries, at least for hashrocket alignment

something that seems semi related to this is that if I have another resource further down the file and i hit gqi} inside that resource, the function call also gets realigned, which is not what I've asked the command to do -- the movement specified i} should limit processing to inside of a {} block.

example:

longer_function_name('some value', 'some other value', { 'blah' => 'moo' })    
ensure_resource('file', '/something', { 'ensure' => 'file' })  
# other content  
someresource { 'title':  
  ensure => present,  
  long_param_name => 'blah',  
}

with the cursor placed on ensure (or anywhere inside that resource definition), press gqi}. the result is this (see the function call for ensure_resource:

longer_function_name('some value', 'some other value', { 'blah' => 'moo' })      
ensure_resource('file', '/something', { 'ensure'                => 'file' })  
# other content    
someresource { 'title':    
  ensure          => present,  
  long_param_name => 'blah',    
}
